One of his main challengers - if you can call him that - throughout the year was the 42-year-old Alonso, particularly in the first half of the season. The two-time world champion looked like the most likely to spring an upset on Red Bull after being rejuvenated by his new Aston Martin team.
The Italian made the comments while talking about his dream team of drivers, if they all were given the same car.
Speaking to DAZN, he said: "Oscar [Piastri] is talented and let me say intelligent. His brain capabilities are very high. He has very interesting characteristics. I would say that he is very calm.
“Lando is already one of the best drivers on the grid. He is very fast, very good in the race, with tyre management.
"When I think about Lando, I think that if the team and I gave him a good car, he would be able to fight for the championship.
"When we talk about being the most complete, I definitely think of Fernando Alonso. He basically has no weaknesses. I think this makes him unique. He is not the best in many things, but he is very strong in all of them.
"I think that in Oscar I see his powerful mind. He is definitely like Fernando. He can do mathematical calculations while driving.
"On the other hand, Lando, I think his development as a driver will make him so complete. He reminds me a little of Fernando. My top three drivers with the same cars would be Max Verstappen, Lando Norris and Fernando Alonso."
